Introduction

Cisco offers a comprehensive range of pluggable optical modules for the Cisco ONS family of multiservice platforms. The wide variety of modules gives you flexible and cost-effective options for all types of interfaces. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+ pluggable modules. These small, modular optical interface transceivers offer a convenient and cost-effective solution for an array of applications in the data center, campus, metropolitan-area access and ring network, storage area network, and long-haul network.

Technical Overview

SFP Module

An SFP transceiver module (Figure 1) is a bidirectional device with a transmitter and receiver in the same physical package. The module interfaces to the network through a connector interface on the electrical ports and through an LC termination connector on the optical ports. Electrical interfaces and dimensions are defined in the SFF-8472 industry-standard multisource agreement (MSA).

XFP Module

The XFP transceiver module (Figure 2) is a bidirectional device with a transmitter and receiver in the same physical package. The XFP module contains a 30-pin surface mount connector on the electrical interface and a duplex LC connector on the optical interface.

SFP+ Module

An SFP+ transceiver module (Figure 3) is a bidirectional device with a transmitter and receiver in the same physical package. The module interfaces to the network through a connector interface on the electrical ports and through an LC termination connector on the optical ports. It is identical in size to SFP modules, but capable of 10-Gbps transmission.

CXP Module

An CXP transceiver module (Figure 4) is a bidirectional device with a transmitter and receiver in the same physical package. The module interfaces to the network through a connector interface on the electrical ports and through a multifiber push on (MPO) termination connector on the optical ports. It is dedicated usually for 100-Gbps transmission, and it is only capable of 100GBASE-SR10 connectivity.

CFP Module

A CFP transceiver module (Figure 5) is a bidirectional device with a transmitter and receiver in the same physical package. The module interfaces to the network through a connector interface on the electrical ports and through an MPO or LC connector on the optical ports. The electrical connection of a CFP uses 10x10-Gbps lanes in each direction (receive and transmit), while the optical connection can support both 10x10-Gbps and 4x25-Gbps variants of 100-Gbps interconnects (typically referred to as 100GBASE-SR10 and 100GBASE-LR4 in 10 km reach).

Cisco CPAK 100GBASE fiber modules offer a selection of high-density 100-Gbps connectivity solutions. By using CMOS photonics technology, Cisco CPAK is smaller and consumes significantly less power than alternative form factors (Figure 7). They are fully interoperable with other IEEE-compliant interfaces.

Pluggable Modules: List and Description

Cisco ONS Family modules have well-defined product IDs, making it easy for you to order the appropriate module.

The product ID is structured as follows: ONS-AB-CCC-DD. The variables in the ID include:

●For the A variable: S stands for SFP, G for GBIC, X for XFP, and SB+ for SFP+.

●For the B variable: C stands for commercial temperature (0 to 70°C), E for extended temperature (-10 to 85°C), and I for industrial temperature (-40 to 85°C).

Cisco offers two types of video SFP modules, one for transmission and the other for reception of video. The video protocols supported by this pluggable is High Definition (HD) 3G, Standard Definition (SD) Serial Digital Interface (SDI). Table 14 lists the details.
